SVF24-3,81

SVF24-3,81 is a three-phase bridge rectifier module that can operate at up to 3,81 A of DC output current. It consists of two thyristors connected in series in a bridge configuration, plus additional circuitry such as snubbers and antifuses. It is designed to convert alternating current (AC) into direct current (DC). The primary application of this module is in switch mode power supplies as well as some motor control applications.

The working principle behind the SVF24-3,81 bridge rectifier is based on the current-voltage characteristics of a diode. The bridge rectifier consists of two parts, an input stage and an output stage, connected in a bridge circuit arrangement. The AC voltage is connected to the input stage, which contains two diodes arranged in anti-parallel pairs. When the polarity of the AC voltage is one way, the diode pair conducts, allowing current to flow, but when the direction of the AC voltage changes, the other diode pair will conduct, turning off the current flow in the opposing direction. This allows the AC voltage to be converted to a DC voltage.

The output stage consists of two thyristors connected in series. The thyristors act as switches that can be used to control the amount of current flowing through the bridge rectifier. The thyristor is controlled by a gate voltage, which can be set to turn the thyristor on or off, to allow or restrict the flow of current. The thyristors also provide protection if the system is overloaded as they will open up if the current exceeds a certain level.

The SVF24-3,81 bridge rectifier can be used in a variety of applications, but is most commonly used in switch-mode power supplies and motor controllers. In these applications, the bridge rectifier is used to convert AC power into a DC voltage that can be used to power other components. In motor controllers, the bridge rectifier is used to control the speed and direction of the motor by varying the gate voltage applied to the thyristors.

The SVF24-3,81 bridge rectifier is a versatile and reliable device that provides efficient power conversion from AC to DC. It is a simple and cost-effective solution for switch-mode power supplies and motor controller applications.
